sciaims, c1;"5 zo) This invention relates to tool sharpeners of that general class shown and describedin my co-pending application, filed in the U. S. Patent Office on the 14th day of June, 1934, bearing 5 :Serial Number 730,670, thepresent invention being an improvement thereon.

'The object of the invention is generally to im-' prove and increase'the utility and efiiciency of V :the -tool by providing means wherebythe abrad- 1 j ing element may be quickly and conveniently adjusted at different angles with respect to the tool supporting surface to accommodate tools having different angular cutting edges without changing the position of the abrading holder with respect to said supporting surface.

A further object of the invention is toprovide a scissors sharpener having an abrasive carrier mounted for oscillation within the holder and provided with means whereby the carrier may be clamped at the desired position of adjustment within the holder. 1

A further object is to provide a novel form of clamping device which serves a dual function of simultaneously holding the abrading element & within the carrier and clamping said carrier within the holder.

Further objects and advantages are set forth in the accompanying specification. V In the accompanying drawing forming a part of 36 this specification and in which similar numerals of. reference indicate corresponding parts in all the figures of the drawing,

Figure l-is a side elevation of a toolshapener embodying the present invention and showing 3% the manner of using the same.

Figure 2 is a top plan'view,

Figure 3 is a transverse sectional view taken on the line 3-3 of Figure Figure 4 is a vertical sectional view taken on 46 the line 4- 4'of Figure 3. i 1 V Figure 5 is a transverse sectional view showing a modifiedform'of clamping screw.

The improved scissors sharpener, forming the subject-matter of'the present invention, com- 45 prises a solid body portion 5 preferably substantially rectangular in shape, as shown, and formed of metal, bakelite, or other suitable material. Extending from the upper portion of the body 5 and preferably integral therewith is an over- 50 hanging hook-shaped member constituting a oscillation a correspondingly shaped abrasive carrier l0. One side ofthe carrier H3 is formed with aflat face H and opening through said flat face is a substantially rectangular recess I 2 adapted to receive a block of abrasive material, indicated at E3. The holder 6 near the hooked end thereof is provided with a slot M and operating in said slot is a clamping screw l5, one end of which is provided with a finger piece 16, while the other end thereof is threaded in an opening H in the carrier with the flat terminal I8 of the screw bearing against the adjacent surface of the abrasive block, as best shown in Figure 3 of the drawing. Each end of the abrasive carrier is stamped or otherwise formed with a pointer l9 adapted to register with grad-nations or numerals formed on the holder 6 for indicating different positions of adjustment of the abrading element with" respect to the tool supporting surface 8 of the body. 20 It will here be noted that the clamping screw 15 serves the dual function of holding the abrading element l3 within the carrier and clamping the carrier in a set position Within the holder. Furthermore, the finger piece l6 provides a convenientmeans foroscillating the abrasive carrier within its seat when adjusting the abrading element to accommodate scissors or other tools having different angular cutting edges. The body 5 at its junction with the holder is formed with a relatively deep depression 2| adapted to receive the forefinger while the side walls of the body may be formed with shallow recesses to receive thethumb and middle finger of the user.

In operation, the sharpener is grasped between the fingers in the manner shown in Figure 1 of the drawing and said sharpener positioned over oneof the blades of a pair of scissors, indicated at 22. The clamping screw i5 is then loosened and the carrier, together with the abrading block, 40 adjusted within the holder until the active face of the block of abrasive material coincides with the bevel -or inclination of the cutting edge of the scissors blade after which the clamping screw is tightened which holds'the abrading block against displacement and firmly clamps the carrier against the walls of its seat in the holder. The tool is then reciprocated longitudinally of the scissors blade in the usual manner until the cutting edge thereof is sharpened to the desired degree. It will here be noted that the tool supporting surface 8 overhangs the seat 9 and intersects the active surface of the abrading block at one side of the medial line thereof so that should one portion of the abrading block be- 7 to lock the carrier in adjusted position.

It will, of course, be understood that the tool sharpeners may be made in different sizes and shapes and formed of any suitable material with-- out departing from the spirit of the invention. It will also be understood that. while the tool sharpener is especially designed for sharpening scissors, said tool may be used with'equally good results for sharpening any kinds of edged tools.
